When it comes to tough jobs and high-performance parts, not all aluminum is created equal. Enter 7075 aluminum—the powerhouse alloy used everywhere from aerospace components to racing parts. If you're looking for OEM CNC machining services that work with 7075 and care about corrosion resistance, you’re in the right place.
Why 7075 Aluminum? Simple. It’s Strong, Light, and Reliable.
7075 aluminum is known for one thing: strength. This is the same grade of aluminum that’s used in aircraft wings, bike frames, and performance automotive parts. It's part of the 7000 series—aluminum alloys that include zinc as the primary alloying element. That gives it near-steel strength without the weight.
Here’s what sets it apart:
- High strength-to-weight ratio
- Excellent fatigue resistance
- Good corrosion resistance (especially when treated)
- Great for structural applications
CNC Machining 7075 Aluminum
Machining 7075 aluminum takes skill. It’s not the soft, forgiving kind of aluminum like 6061. It's tougher, a bit more demanding, and needs the right tools and settings to get clean cuts and tight tolerances.
That’s why working with a trusted OEM CNC machining service is key. They’ll know how to:
- Prevent warping during cuts
- Maintain tight tolerances on complex parts
- Finish the surface properly (especially for anodizing or coating)
- Reduce waste and improve repeatability
Whether you're making brackets, housings, bushings, or mounts—precision is everything.
Corrosion Resistance – Not Just a Bonus, a Must
Even though 7075 has solid corrosion resistance on its own, many OEM services finish the parts with anodizing or chemical conversion coatings (like Alodine) to boost that protection even more.
This matters a ton for:
- Outdoor or marine use
- Aerospace environments
- Automotive or racing parts
- Electronics housings exposed to moisture
your parts last longer, look better, and stay stronger when corrosion isn’t eating away at them.
Common Applications of 7075 CNC Parts
This alloy isn’t for every job—but when you need it, you really need it. Some real-world uses include:
- Aerospace parts (aircraft fittings, structural components)
- Bike components (stems, handlebars, frames)
- Motorsports (suspension arms, engine mounts, brackets)
- Defense gear (optics mounts, rail systems)
- Robotics and automation (high-stress joints and arms)
These are parts that live under pressure, and 7075 doesn't flinch.
